700 * 3 =3D 2,100 KB/sec. It looks as if you're running either a 10MB
line and/or have the duplex set to auto or even to half duplex. I'm
supprised that you don't want to use optimizations - we have seen
significant improvements with them. Also, streaming to one drive is not
productive. We currently have a mix of over 129 servers (SUN, SGI, W2K,
and RH LINUX) running and we saw thruput as high as 44,089.00 KB/sec on
todays run.

Subject: [Veritas-bu] Unix backup performance...
=09
=09
We just added 3 Solaris8 systems to our backup. What changes
need to be made to produce reasonable performance? I am running a test
backup now.
The Master is a Quad Windows2000 SP4 running NBU Datacenter
4.5_FP6
The Media servers is a Dual Windows2000 SP4 running NBU
Datacenter 4.5_FP6. It has a Dell PV-132t with 2 Gen 2 LTO Drives in
it. I have all 3 machines streaming to a single drive. I am getting
~700 kbs each.
The clients are Sun Solaris8 machines running the NBU 4.5_FP6
client.
We get a higher throughput from our windows clients. We have
*no* files and buffers optimizations done and at this point really don't
want to go down that road. They are backing up via the network.
Thanks
